How did B.F. Skinner categorize verbal behavior?

B.F. Skinner categorized verbal behavior primarily by the function of the behavior, rather than its form. This approach highlights how language is used for specific purposes and how that usage influences the development and understanding of verbal communication. For Skinner, verbal behavior includes any form of communication that serves a particular function, such as requesting, labeling, or asking questions. This functional analysis emphasizes the role of the environment and social interactions in shaping language use, which is a central tenet of his behaviorist perspective.

The focus on function allows for a broader understanding of communication, moving beyond simply analyzing the words or structure of speech. By considering what a speaker is trying to achieve with their verbalizations, one can better understand the underlying motivations and contextual factors that influence language. This perspective marks a significant departure from more traditional approaches that may focus solely on the content or grammatical aspects of speech.
